Sunex 884505 3/8 aandrijving 9/16 extra diep bougiestekker, CR-MO

Worked well changing spark plugs for the 4.6l 3V V8 engine in my 2010 Explorer Sport Trac. I was surprised to find that the motor has a nonstandard plug size; neither the 5/8" plug socket I owned for previous cars nor the 9/16" plug socket that I picked up at a local auto parts store would work. So I ordered this one, and I was happy to find that it did the job just fine.I needed to use a few different extensions, and the jointed ones made a couple of the rear plugs easier, but it's not a challenging task as far as auto maintenance goes.All in all, it was a pretty straightforward job with this tool. It held onto the plugs securely coming out and going back in, which is the main concern with a socket like this. No problems with cross threading or anything, and I didn't even need anything to penetrate and loosen them before removal.A helpful reminder for this type of job: Just be sure you use some strong compressed air to blow out any wayward debris after you pull each coil but before you loosen the spark plug. You don't want those pebbles and dust falling down into the top of the motor. Or so I'm told.

A perfect fit and length for these spark plugs. It worked out perfectly for the job.

Works good for long hole spark plugs

This socket is very well made and perfectly suited to the dreaded Ford 5.4 3-valve plug replacement. I used with a combination of 5/8 deep and shallow well impact sockets (removing plugs) and a 3/8 extension for (hand starting and torquing). The hot plug method worked perfectly for me (see FordTechMakuloco on **utube - worked 8 out of 8) and the socket held up and worked flawlessly and held onto each of the plugs out after they were unthreaded with my stubby impact. I dreaded this job for a week and it only took a couple of short hours, including the test drive. Don't forget the nickel anti-seeze and the Motorcraft dielectric grease for the COPS. I can't speak highly enough of this quality tool.

Able to remove spark plugs without extension.
